Answer:

Maria purchased 9 CDs

Step-by-step explanation:

Maria spends $84.00 on CDs. The first CD is $12,  the rest $9

As the CD have different price ,  first we have to discount the price of the first one,  and then we divide the rest by $9

Price First CD = $12 ,

We buy the first ,  so we get the rest of money  84-12=72

Price Rest =$9 ,  with the money that left ,  we can buy 72/9= 8

Total= 1 +8 =9

The interior angles of a triangle have measures k°, 27°, and 10°.<br><br> What is the value of k?
NikAS [45]

Hey!

Hope this helps...

~~~~~~~~~~~~~~~~~~~~~

Assuming that the sum of all the angles must equal 180°

180 - (27+10) = k

180 - 37 = k

k = 143°

The diameter of a circle is 8 feet. What is the angle measure of an arc a feet long?
fiasKO [112]

Answer:

Given: circle

diameter = 10 cm => radius (R) = 5 cm

Find: measure of angle bounding sector = 11 π sq. cm.

Plan: determine what part of the circle’s total area equals the sector’s area.

Total Area of Circle A = π R^2 = π 5^2 = 25 π sq. cm.

Therefore: Sector Area = 11 π cm^2/25 π cm^2 = 11/25

Since the sector is 11/25 th of the circles area, the sector angle will measure 11/25 th of the circle’s circumference. They are proportional.

C = 2 π R = 2 π (5) = 10 π cm

Sector Arc = measure of sector angle = 11/25 (10 π) =

22π/5 radians

Answer: Sector Arc = 22π/5 Radians

Write the slope-intercept form of the equation of each line given the slope and y-intercept
amid [387]
The slope-intercept form of the equation for a line is ...
  y = (Slope)x + (y-intercept)

Put the given information in the appropriate spot in the equation. Simplify as required.
  y = (-1/3)x + 0
can be simplified to

y = (-1/3)x

What is the experamental probability that the coin lands on heads?
sammy [17]

Answer:

The experamental probability that the coin lands on head is 50 %

Step-by-step explanation:

Given:

Experiment:

A coin is Toss

Let the Sample Space be 'S' that is total number of outcomes for a coin has been tossed = { Head, Tail }

∴ n ( S ) =  2

Let A be the event of getting a Head on tossing a coin i.e  { Head }

∴ n( A ) = 1

Now,

\textrm{Probability} =\frac{\textrm{outcomes for the experiment}}{\textrm{total number of outcomes}}

Substituting the values we get

P(A) = \frac{n(A)}{n(S)} \\\\P(A) = \frac{1}{2} \\\\P(A) = 0.5\\\\P(A) = 50\%

The experamental probability that the coin lands on head is 50 %
